Wind turbines are the conventional type of energy source. The main focus of this work is the analysis and fabrication of cost effective VAWT. Cost of the turbine is reduced by low cost material and minimizing its total weight. There are two main types of the wind turbines i.e. Horizontal ... En savoir plus
Our laboratory is currently leading the design and the manufacture of a novel device that allows NMR spectroscopy to be cooled down to cryogenics temperature (in the 10-100 K range). The system features a sample-holder that rotates at very high frequencies (f >10 kHz). Two aerostatics ... En savoir plus
Verifying that a local software installation performs as the developer intended is a potentially time consuming but necessary step for safety related codes. Automating this process not only saves time, but can increase reliability and scope of verification compared to ‘hand’ comparisons. ... En savoir plus
Three dimensional mathematical models are developed to simulate the blood flows in patient specific right coronary arteries with two stenoses. Simulations are carried out with various flow parameters under physiological conditions. Both Newtonian and non-Newtonian blood viscosity models ... En savoir plus
The particle tracking model provided a deeper understanding to the experimental results. The model showed good agreement with experimental data for rotation, transport and attachment. In the attachment model, protrusions create low velocity, low shear regions increasing attachment ... En savoir plus
The radio-frequency(RF) plasma sources have shown great potential in various industrial applications such as thin coatings deposition and polymers modification[1,2]. Physics of low pressure RF plasmas has been investigated significantly[3]; however, this kind of plasma source is rarely ... En savoir plus
A new regulation for the safety assessment of dams has just been developed in Italy and its approval process is still in progress. As a matter of fact the behaviour of dams under seismic loading conditions is deemed of actual interest due to the recent seismic events occurred. In ... En savoir plus
A grand variety of microactuator technologies and demonstrators has been introduced during the last years. Of particular interest are the microactuators based on phase change materials and especially paraffin wax, which can volumetrically expand up to 15%, providing high force actuation. ...

Excessive air damping can be detrimental to the performance of oscillating MEMS components. Complex systems, such as structures in pre-etched cavities or angular comb-drive scanning mirrors, typically require simulations to reliably evaluate the air damping. The simulated and ... En savoir plus
Precise electrochemical machining (PEM) is a non-conventional machining technology, based on anodic dissolution of metallic work-pieces. In this study an additional extension of the precise electrochemical machining with a precise angle-controlled cylinder positioning is aimed. Due to ... En savoir plus
